Weak stability and random mean-field limit of the phase-spatially extended kinetic Cucker-Smale model

Seung-Yeal Ha, Xinyu Wang

We study the weak stability of the kinetic Cucker-Smale (in short, KCS) model in a phase-spatially extended setting, which can be formally derived from the infinite Cucker-Smale mo…

Uniform-in-time stability and mean-field limit of the Cucker-Smale-type model with noncompact support

Seung-Yeal Ha, Xinyu Wang, Wook Yoon

We study the uniform-in-time stability and mean-field limit of an infinite Cucker--Smale-type (ICS-type) model in a fully noncompact setting. First, we clarify the main difficultie…

Emergent behaviors of the singular continuum Kuramoto model and its graph limit

Li Chen, Seung-Yeal Ha, Xinyu Wang +1

We study the emergent dynamics of the singular continuum Kuramoto model (in short, SCKM) and its graph limit. The SCKM takes the form of an integro-differential equation exhibiting…

On the weak flocking of the kinetic Cucker-Smale model in a fully non-compact support setting

Seung-Yeal Ha, Xinyu Wang

We study the emergent behaviors of the weak solutions to the kinetic Cucker-Smale (in short, KCS) model in a non-compact spatial-velocity support setting. Unlike the compact suppor…

Emergent dynamics of spatially extended relativistic kinetic Cucker-Smale model

Seung-Yeal Ha, Xinyu Wang

We study the emergent dynamics of the relativistic kinetic Cucker-Smale (RKCS) model without assuming compactness in spatial and velocity support. In this setting, the lower bound…
